NAME¶

std::filesystem::path::root_directory - std::filesystem::path::root_directory

Synopsis¶

path root_directory() const; (since C++17)

Returns the root directory of the generic-format path. If the path (in generic
format) does not include root directory, returns path().

Parameters¶

(none)

Return value¶

The root directory of the path.

Exceptions¶

May throw implementation-defined exceptions.

Example¶

// Run this code

#include <filesystem>
#include <iostream>
namespace fs = std::filesystem;

int main()
{
fs::path p = fs::current_path();

std::cout << "The current path " << p << " decomposes into:\n"
<< "root name " << p.root_name() << '\n'
<< "root directory " << p.root_directory() << '\n'
<< "relative path " << p.relative_path() << '\n';
}

Possible output:¶

The current path "C:\Users\abcdef\Local Settings\temp" decomposes into:
root name "C:"
root directory "\"
relative path "Users\abcdef\Local Settings\temp"
